Abstract:

An active control type anti-yaw damper (100). A piston (2) of the active control type anti-yaw damper (100) divides the interior of a hydraulic cylinder (1) into two cylinder bodies (PA, PB) when reciprocating in the hydraulic cylinder (1), wherein the two cylinder bodies (PA, PB) are respectively communicated with an oil storage tank by means of two main oil passages, so as to constitute a main loop between the hydraulic cylinder (1) and the oil storage tank; a reserving valve (PV3) is mounted between the two main oil passages and the oil storage tank, used for changing a flow direction of the main loop when the active control type anti-yaw damper (100) is in an active mode, and can adjust the displacement of the piston (2) in the hydraulic cylinder (1).
